A Comment on ‘Buyers' Miscoordination, Entry and Downstream Competition’
评论Fumagalli和Motta（2008）关于下游竞争限制上游垄断企业阻止更高效竞争者进入的观点，指出竞争可能因“提高对手成本”效应促使买家偏好在位企业。
Abstract Fumagalli and Motta (The Economic Journal, 2008) argued that competition among downstream buyers limits the ability of a dominant upstream firm to deter entry by a more efficient competitor. This comment demonstrates that the impact of downstream competition is, in fact, more complex. In particular, competition can motivate buyers to favour the incumbent due to a ‘raising rivals’ cost’ effect.
